MS0040-E-01
Notes:
- LRCK = fs, BICK = 64fs.
- Power lines of AVDD and DVDD should be distributed separately from the point with low impedance of regulator
- AVSS, BVSS and DVSS must be connected to the same analog ground plane.
- When AOUT drives some capacitive load, some resistor should be added in series between AOUT and capacitive
- All input pins except pull-down/pull-up pins should not be left floating.
